I was looking at the .44s and notice that you make pretty much the same as everyone else. Will you ever tool up for heavier bullets, 300+ grain?
Now if they could do something about the boxes. I still haven't figured out how to open them.
12 Hardness: <1,000fps
18 Hardness: <1,500fps
18+ with Gas Check: 1,500fps+
I'm new at this..... On there website for 45 ACP Brinell 18 is for Major Power factor and Brinell 12 is for Bullseye or Target velocities. Now to get major for Most ISPC, USPSA, and IDPA all there bullets (185, 200, 230) not need pushed past 1000 fps. So..... Is 18 really nessicary or?
Take a typical .45 ACP load, using a 200-grain LSWC bullet – 5.0 grains of Bullseye. This load develops 900 FPS and is in common use among IPSC and IDPA gunners. The reloading manual shows that the pressure generated by this load is 20,000 CUPS. So, the formula for optimal bullet hardness is
20,000 / 1279.8 = 15.62
There it is! For this application – shooting a 200-grain LSWC at 900 FPS requires that you use a bullet with a BHN of 16 to 18 (round upwards a couple of BHN points for flexibility.)
Which would give you 12.7 instead of 15.62 for a load that is ballistically similar.200 GR. CAST LSWC - HS-6 - 8.4gr - 907fps 16,300 CUP
